Unonopsis aurantiaca

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Unonopsis aurantiaca faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Amazon basin. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and infrastructure development further threaten the integrity of its lowland rainforest habitat, while climate change may alter the specific microclimatic conditions this endemic tree requires for survival.

Threat summary

Habitat

Unonopsis aurantiaca inhabits primary lowland rainforests of the Amazon basin, typically occurring in well-drained soils of terra firme forests. The species is found in the understory and canopy layers of undisturbed tropical rainforest ecosystems, where it requires specific humidity and temperature conditions characteristic of intact Amazonian forest environments.
